Tube Clamp 219 Slope Socket- An adjustable cross for connecting tubes between mid/lower rails and the vertical on ramps or shallow gradients. The vertical must remain continuous with the cross rails being cut. Tube Clamps are a simple and cost effective way of creating an endless variety of tubular structures without the need for welding. Our extensive range of handrail fittings when combined with standard EN10255 tubing enables the user to create any structure imaginable for use in all manner of industries. Tube Clamp fittings are a black-heart malleable iron casting manufactured to BS EN 1562:1997 using grade B32-10 material with a hot dipped galvanized finish to BS EN 1461:1999. All Tube Clamp fitting are supplied with stainless steel grub screws. In order to protect any exposed threads in outdoor installations, we recommend the use of an anti-corrosion galvanizing spray such as the one sold as part of our Tube Clamp range. The grub screws can be tightened with an Allen key, however, if fully tightened using a ratchet key to a torque of 4.1kg/m the grub screw is capable of withstanding an applied slip load of 900kg.
